How do you rank light needs? -OR- making lemonade out of toxic roof cleaning solution

[DirtyCoconuts]

SO this is a dual purpose thread- one because i am looking for insight about how to arrange plants by light needs and also, slyly, to show off how i have re-arranged the grow spaces in my yard for better control and protection

i have my Schom/ myr species and hybrids out getting max light;
then, very close is the area where the catesetums go;
next highest light is the brassavolas and hybrids- this includes Bc. and Blc. hybrids.

next i have catts and catt hybrids. i include catt, leilia, Rlc. Lc. in this group.

another area has dendrobiums (phal type and laurinatre and aussie)

then i have the lath house which has a sunny side and shady side and the sunny side has the antelope dens and the "chip" family of dens as well as the zygotes and miltons as well as neos

shady side has the phals and the bulbos and there are oncidiums moving around as they confuse me the most


any glaring errors you see? suggestions
